H.264/AVC error detection scheme using fragile data hiding in motion vector set
ABSTRACT
The corruption of compressed video bitstreams during transmission over error-prone communication channels leads to the degradation of visual quality. To effectively conceal the corrupted video data, an exact error detection scheme is more important than anything else. In this paper, we propose a new error detection scheme using fragile data hiding technique to improve the error detection ratio. Experimental results show that the detection ratio of the proposed algorithm is about 88% although the proposed scheme brings on the small increment of bitrate and decrement of PSNR in process of encoding.
